Mr Row asked Dr Pritchard why she had not employed an electrostatic detection
advice - a handwriting analysis machine - to examine the signatures.
Mellinger had an idea: electrostatic detection analysis.
After he filed his request, a document forensics expert at the Archives examined the Haldeman notes, found indented writing on the second page, and concluded that electrostatic detection analysis could work on this document, according to Paynter.
Mellinger has convinced the archives to subject the existing notes to electrostatic detection
analysis, which can capture indentations on paper.
This was established by using an electrostatic detection apparatus procedure, which produces a record of what is indented into a piece of paper.
In addition to electrostatic detection apparatus, a video spectral comparitor can be used to illuminate inks based upon their formulations, which can differentiate inks and enhance alterations or erasures.
A series of tests including handwriting, ultraviolet light and electrostatic detection
were carried out on the five documents.
I work in a laboratory and on a regular basis use a machine called an Electrostatic Detection
Using specialized photography, microscopes, and an electrostatic detection
apparatus that can reveal where information has been obliterated, erasures were detected on the original.
He also conducted an indentation analysis of the court document using an electrostatic detection
device, which revealed the paper bore indentations "consistent with someone practicing the writing of a signature before actually simulating the signature.
Students employ a range of the latest chromatographic techniques to analyse unknown materials, use scanning electron microscopy to examine traces residues and electrostatic detection
apparatus to investigate document fraud.
